Question 52

Subtraction should be used to check if the difference of two values is greater than 1.

To determine if the difference between two values exceeds 1, subtraction is the appropriate operation since it calculates the actual difference between the two values.

A) Addition

Addition is the operation of combining two values, which does not provide information about their difference. Therefore, it is not suitable for checking whether the difference between two values is greater than 1.

B) Multiplication

Multiplication involves scaling one number by another and does not relate to finding the difference between values. Consequently, it cannot be used to determine if the difference is greater than 1.

C) Subtraction

Subtraction directly calculates the difference between two values, making it the correct operation to check if that difference is greater than 1. By subtracting one value from another, we can easily assess whether the result exceeds the threshold.

D) Division

Division calculates the ratio of one number to another, which does not provide insight into the difference between two values. Hence, it is not relevant for determining if their difference is greater than 1.

Conclusion

Subtraction is the only operation that directly evaluates the difference between two values, making it essential for checking if this difference exceeds 1. All other options, addition, multiplication, and division, do not provide the necessary calculation to address the question accurately. Thus, option C is definitively the correct answer.
